Community Liaison Group

Eden Geothermal Community Liaison Group aims to provide “a forum for communication between Eden Geothermal, its partners and the local community”. Its members are representatives of the four parish councils that border the Eden site (Treverbyn, Luxulyan, St Blaise and Carlyon), Cornwall Council, Eden Neighbours Forum, Eden Geothermal Ltd and Eden Project.

More information about how the group operates can be found in EGCLG’s Terms of Reference, which you can download here:

Latest updates


Programme update

The geothermal site is nearing completion, and we are working towards the drilling rig arriving in late April / early May. The rig will arrive in a number of containers and will take around 3 weeks to construct on site before drilling starts. We hope to announce a firm spud date and more detail very soon!


Temporary road closure

Openreach have informed us that the road between Eden Project’s north gate and Trethurgy (first junction) will be closed between 11th and 14th March 2021 while the geothermal site is connected to the network. We’re sorry for any inconvenience.


Site progress and update on drilling start

Arrival of the drilling rig has been delayed due to complications around the pandemic and Brexit restrictions, but we now anticipate it arriving in April. (We will post an update when dates are confirmed.) Site works have been progressing well, with the arrival of the temporary offices on site, ready for connection to services.

The retaining wall to the north of the lagoon is complete, and the team have been working on the south embankment.

The drilling containment area has been lined to create an impermeable barrier, and the area between the rig pads is ready to be concreted.


Conductor installation rig arrives on site

The conductor installation rig has arrived on site. This will drill a hole a few tens of metres deep to enable installation of the conductor pipe. The conductor pipe is installed down to competent bedrock and forms the start collar for the well by isolating the loose weathered ground near surface.

The rig will start drilling over the coming few days, and the operation is expected to take about 3-4 days. Then the conductor installation rig will leave the site.


Site Works

Last week the main loadbearing areas of the rig pads, which will support the rig during drilling, were concreted. Work also continued on the water storage lagoon. Site works will resume in the New Year after the festive break.


Site Works

Last week the shuttering was removed from the new well cellars. They’re in!

And stable foundations for the rig were created by driving gravel ‘pilings’ into the rig pad area.

This week, Jason and the team are trenching for the water and power supply. Using the window in which Eden Project is closed to visitors means they’re able to avoid any disruption to traffic flow on the Eden access road.


Site Works

Work started to prepare the site, just inside the north entrance to the Eden Project, in late September.

In the operations and access areas, the ground has been levelled, drainage has been improved and stone has been laid.

The drilling area itself, where the rig will sit, was formerly a landfill site. This area has been filled and compacted, and work is underway to construct two well cellars at the site of the first and second wells. Although we’re only drilling one well initially, constructing both cellars now will mean things can progress more efficiently for the second phase.

The well cellar is a dug-out area below the main substructure of the drilling rig. It is constructed of concrete rings. During drilling, it houses the initial conductor pipe, and later it will accommodate the wellhead – a set of large valves that sits directly on top of each well. Each well cellar is 4 m deep and 3 m in diameter, but the well itself will be only 9” (under 25cm) in diameter at the surface.
